•  interactive development (Slime / top-level with a running Qt event loop)
      •  cross-platform (tested: Linux, OSX, Windows)
      •  no external dependencies (Lisp/C++ libraries/parsers)
      •  overriding virtual Qt functions
      •  unicode
      •  translations (Qt Linguist)
      •  loading UI files (Qt Designer), optionally converting x.ui to x.lisp
      •  simple encapsulation in Lisp classes
      •  easily embeddable in existing Qt/C++ projects
      •  experimental: usable from any CL + CFFI (through a local server)
